Debian Configuration :: Install A Multi-core System And Configure It To Run Several VMs, One Each For A Firewall, A Caching Proxy Server, A Mail Server, A Web Server?
Jan 25, 2011I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
Server :: Persistent Caching Proxy Available To Configure ?
Nov 29, 2010Is there anything like a persistent caching proxy available in linux for me to configure, ie not public? (persistent meaning the cache remains in hard disk between reboots) Is it possible that it NEVER looks for any update to a page that is available in the cache?

Dec 17, 2010I have a Bind DNS caching-only server setup that is working. I am bringing up a new AD domain controller that will also be a DNS server for that AD but I don't want it responding to any DNS queries except those that are AD related.So, my goal is to leave this caching server as the primary DNS server for stations on the network and have it forward requests for the AD domain to the domain controller.My understanding is that I just need a forward zone for that domain pointing to the domain controller. However it does not seem to be working.So that leaves me to think that my caching server is not forwarding properly.
For example, this AD is going to have a naming convention of hostname.mydomain.local.If I do an nslookup and specify the domain controller's IP address as the server, I can query addresses that exist in DNS on that server, such as dc1.mydomain.local.However, queries to my caching server times out (I get a response from the caching server if I query mydomain.local but none of the objects in that domain) Here is my named.conf file:
options {
directory "/var/named";
listen-on { 192.168.0.14; 127.0.0.1; };
[code]....
Server :: Dns Server - Caching - Not Working ?

I checked /var/log/messages on my machine and there were two kinds of messages:
Now there are a lot of errors of the above two kinds only. The only difference in the errors are the ip address that is different.
Red Hat :: Caching Name Server DNS
Sep 25, 2009I am trying to setup a Caching-Name Server for my lab but I am unable to locate the named.caching-nameserver.conf under /etc directory.

Feb 12, 2009I am looking into creating a web caching server for myself using fedora 10. I believe I need to use squid for this but it seems to have a lot of features. Basically, all I want for now is to be able to cache web pages that I and my network users use the most, increasing access time and lowering the load on my internet connection. Can squid do this and can someone point in the right direction on an article on how to configure such a thing?
View 5 Replies View RelatedServer :: Directory Attribute Caching For NFS/GlusterFS?
Sep 3, 2010Basically, i have a clustered filesystem using GlusterFS. This is ultimately going to host a very large number of files.
It is mainly used as a storage destination for backups, and historical copies of files.
Remote servers sync using unison every few minutes. A local script will run over the whole filesystem once per hour looking for new files/folders, and files that have been updated based on their timestamp.
99% of filesystem access is browsing the directory structure, listing directory contents and checking the modification times of files. Access to the actual content of a file is minimal. Only a tiny fraction of the filesystem is actually modified from hour to hour.
GlusterFS alone is quite slow when browsing the directory structure. (ie. "ls -Rl /data") The speed of things for actually transferring file content is sufficient for my requirements.
What I need is to vastly improve performance when running operations such as "ls -Rl /data". (/data is the mount point)
I believe the best way to do this is to implement caching. The cache options within GlusterFS are simply not sufficient here.
My first thought was to re-export the GlusterFS mount with NFS, and then mount the NFS share and set the cache on the client to a very long expiry. (like 86400 = 24 hours) It is my understanding that any change made to a file using the mount point will invalidate the cache entry for that file. (it is only mounted in one place, so no changes possible at the back end.)
I did this using the kernel based NFS server, but ran into major problems with the "Stale NFS" errors which from reading is due to a problem related to FUSE that doesnt sound like its going to be fixed soon. Aside from the Stale errors, this did provide a suitable boost in performance.
I tried the beta of GlusterFS that has the integrated NFS server (so presumably, no FUSE) but I could not get this to compile properly on our servers.
Finally, I tried using the Gluster patched version of unfs3 that uses boost to talk to Gluster instead of FUSE. Now this works, but for some reason the NFS client cache doesnt seem to cache anymore.
One last thing that I was looking at is the possibility of running a simple cache layer in front of either GlusterFS or NFS. I believe Cache-FS is the tool for the job but I have been unable to get that to work - I believe it is disabled in my kernel or something. (mount command says cachefs is unknown)
I am running Ubuntu 8.04 on most servers, but have upgraded one to 10.04 to try and get around Kernel limitations. My servers are all 32 bit (I know, not recommended for GlusterFS) and its very difficult for me to change this. (its a live system)
I quite simply need to add a cache for the directory structure information, and then maybe export this with NFS so that it can be mounted on a *single* server. (the cache can be on the server where it is mounted if required, but due to the large size of the cache - it may be better to have a server dedicated for the cache)
I am running GlusterFS 3.0.5 in a replicate/distribute manner.

Sep 5, 2009I've set up a caching nameserver on my laptop running Fedora 11. The problem with this is that NetworkManager always overwrites the entry that points to the local nameserver. NetworkManager no longer respects /etc/dhclient.conf or at least its scripts run after dhclient.conf. Also it doesn't respect /etc/sysconfig/ network-scripts/ifcfg-* setting of DNS{1.2}.The man page of NetworkManager describes scripts that run in /etc/NetworkManager/dispatcher.d which can be run when interfaces are brought up and down. I've written a script that will put the entry needed for the local nameserver.
